– Can cause various health problems

26. Why is it Important to Clean Our Water?
• Arsenic
– Could cause skin damage, circulatory
problems and increased risk of cancer.
• Lead
– Can cause various health problems
• Nitrate
– In drinking water at levels above 10ppm is a
health risk for infants younger than 6 months
of age. High levels of nitrate in drinking water
can cause blue baby syndrome.

30. General Wastewater Treatment

31. General Wastewater Treatment
• All water treatments involve removal of solids, bacteria,
algae, plants, inorganic compounds, and organic
compounds.
– Removal of solids is usually done by filtration and
sediment.
– Converting used water into environmentally
acceptable water is wastewater treatment
